Abstract:
|
Most of the craters on the surface of the Moon were created by the collision of minor
bodies of the Solar System, in particular asteroids coming from the Main Belt as a consequence
of different types of resonance. Our aim is to investigate the dynamics of such asteroids, paying
special attention on the hyperbolic invariant manifolds associated with the equilibrium point
L2 of the Earth – Moon system within the framework of the Circular Restricted Three – Body
Problem. We analyze how different distributions of initial conditions for transit trajectories and
the value considered for the relative Earth – Moon distance can vary the probability of a lunar
impact. Then, we add the gravitational effect of the Sun by means of the Bicircular Restricted
Four – Body Problem, showing that the initial phase associated with the Sun and the ratio
between the Earth – Moon – Sun distance and the Earth – Moon one can affect the collision
pattern in terms of lunar longitude and latitude. |
